Answer:
8xy
Step-by-step explanation:
![\sqrt{(8xy)^{2}}=\sqrt{(8)^{2}x^{2}y^{2}} =8xy](https://tex.z-dn.net/?f=%5Csqrt%7B%288xy%29%5E%7B2%7D%7D%3D%5Csqrt%7B%288%29%5E%7B2%7Dx%5E%7B2%7Dy%5E%7B2%7D%7D%20%3D8xy)
Answer:
-2/3
Step-by-step explanation:
Perpendicular slopes have lines that multiply to -1
m* 3/2 = -1
Multiply each side by 2/3
m* 3/2 * 2/3 = -1 * 2/3
m = -2/3
The slope of the perpendicular line is -2/3
I am sorry but this is incomplete. If you would like to PM me the full question I would love to help?

Answer:
546 ft³
Step-by-step explanation:
In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.
Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²
Area of the rectangle: 1.5*11 = 16.5 ft²
Total area: 120 + 16.5 = 136.5 ft²
Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³
